As a hotel with the parent-child theme, Hangzhou Fuchun Wonderland Resorts has been widely praised since its opening one year ago. However, most visitors felt regretful for the lack of a swimming pool. In early 2019, the owner, after considering several sites, finally decided to build a swimming & fitness leisure center to be interacted and integrated with the Lanjang Tower for sightseeing and recreation. Though located at the top of the end of the hotel area, the Lanjiang Tower is surrounded by woods that largely block the landscape. In addition, due to its single function, the Tower has been neglected regardless of its unparalleled view of Fuchun River and almost been deserted for the isolated existence and few visitors. The swimming & fitness center will link the Tower and the River and truly realizes the unparalleled landscape. Meanwhile, the expansion of the outdoor platform and the setting of shops improve the supporting functions. By adding a streamline to link all these functions, an ideal jigsaw will be completed and expected to be-come a unique must-go of the resorts. A relatively flat land will be cultivated on the hillside facing the Fuchun River by taking the line from the Lanjiang Tower to the south as the central axis. With no damage to the perennial trees and the contour line as the boundary, the land is coincidentally presented as a leaf-shaped boat. Because of the coincidence, it would naturally remind people of the verse of “or to have the boat fully loaded with starlight, and sing aloud in the splendor of starlight” in the poem Saying Good-bye to Cambridge Again. The facility is divided into two layers by combing with the altitude difference of the terrain. The front end of the lower layer will be the fitness center, with the panoramic French casement and a terrace reaching nearly 3 meters out, creating a posture of floating in the air and heading for the Fuchun River. In the end, there is a computer room, changing and shower room and other auxiliary rooms. A boundless swimming pool is set on the upper layer and connects with the Lanjiang Tower by a wooden platform to form a whole. The two big trees reserved perfectly shade the banks of the swimming pool. During summertime, the cool breeze will blow high on the mountain, and the swimmers will rest comfortably under the shade of the trees. As a kind of artificial stone that is simple and elegant, the concrete integrates with the natural environment. In the meantime, the solid part of the main building basically presents the beam-column structure system without decoration, which is also a response to the construction logic. The picture of the starry sky, which is constituted by mosaic tiles and loved by all ages, on the surface of the swimming pool echoes the place and theme to create a unique romantic atmosphere. The scene of “flying clouds in the morning and falling rain at dusk” can always be seen on the Fuchun River, making people feel as if they are in the sea of clouds. The scene integrating stars, clouds, mountains and rivers makes the Fuchun Mountain and River even more beautiful.
